ΟΚΤΑΧΟΡΔΟΝ
The octachordon, a word resonating with the harmony and perfection of ancient Greek music, describes an instrument with eight strings, typically a lyre or kithara. The addition of an eighth string marked a significant evolution in Greek music theory, enabling richer melodies and more complex scales. Its lexarithmos (1285) suggests a synthesis of order and creativity.
REPORT ERRORDefinition
The term ὀκτάχορδον (neuter of the adjective ὀκτάχορδος) primarily refers to a musical instrument, typically a lyre or kithara, possessing eight strings. The word is a compound, derived from the numeral «ὀκτώ» (eight) and the noun «χορδή» (string, gut, chord). In ancient Greek music, the addition of strings to instruments like the lyre was an indicator of musical evolution and increasing complexity.
The traditional lyre typically featured seven strings, and the emergence of the eight-stringed instrument, as attested by authors such as Aristotle and Plutarch, allowed for the performance of more extended scales and the exploration of new harmonic possibilities. This development contributed to a richer musical expression, which in ancient Greece was inextricably linked with poetry, drama, and philosophy.
Beyond its literal meaning as an instrument, ὀκτάχορδον could also denote the quality of being "eight-stringed" in general, i.e., anything composed of or characterized by eight strings or similar elements. As such, the word embodies technical and aesthetic progress in the field of music, reflecting the Greek pursuit of harmony and order.
Etymology
From the root «ὀκτ-» derive many words denoting the number eight or eightfoldness, such as ὀκτάπους, ὀκτάγωνος, ὀκτάεδρον. From the root «χορδ-» derive words such as χορδεύω (to stretch strings), χορδοτόνος (string-stretcher), and χορδοποιός (string-maker). The word ὀκτάχορδον fits into this family as a compound that combines the meanings of both its constituent parts.
